ON FLOW OF ASPHALT

SOME CONCEPTS SUGGESTED TO ANALYZE THE FLOW CHARACTERISTICS OF RHEOLOGICAL MATERIALS WITH EMPHASIS ON THOSE WHICH ARE PROMISING IN THE ANALYSIS OF FLOW ASPHALTS ARE REVIEWED. THE SUGGESTED CONCEPTS ARE CATEGORIZED AS EXPERIMENTAL, MATHEMATICAL/, CONTINUM MECHANICS/, STRUCTURAL /COLLOIDAL THEORY, RATE THEORY OR KINETIC THEORY/, AND PHYSICAL-CHEMICAL. IT IS SHOWN THAT FOR THE TWO ASPHALTS USED IN THIS STUDY, IT IS POSSIBLE TO CONSTRUCT FLOW DIAGRAMS OVER A WIDE RANGE OF SHEAR STRESS, RATE OF SHEAR, AND TEMPERATURE BY USING THREE DIFFERENT VISCOMETERS AND THE PRINCIPLE OF REDUCED VARIABLES. THE APPLICATION OF EYRING>S RATE PROCESS THEORY TO THE ANALYSIS OF ASPHALT FLOW IS EXAMINED AND THE VARIATION OF VISCOSITY, DETERMINED AT CONSTANT SHEAR STRESS OR CONSTANT SHEAR RATE, WITH TEMPERATURE IS DISCUSSED.
